ASH-PIT FOR FURNACES.

SPECIFICATION forming part of Letters Patent No. 347.522, dated August 17 1886.

Application filed May 1, 1886. Serial No. 200,772. (No model.)

.To @ZZ whom it' may concern:

Be it known that I, (JHARLEs T. ScHonN, a

citizen of the United States, residing at Philar ally also the draft-inlet, and hence in order to insure a good draft this pit must be kept clean, which in former inventions could only be done by frequent attendance and use of a shovel to remove the ashes. Furthermore,when ashes are allowed to pile up under and in contact with the grate, their heat has a very injurious effect upon the grate itself, burning it out more rapidly and choking the draft. The removal of hot ashes to bins or barrels is a fruitful source of fires. The manual labor required in shoveling out ashes under old plans, and the dirt and 'dust incident to such plans, have been always a serious drawback to furnaces for heating dwellings. These objections, so far as I am aware, have obtained against furnaces heretofore used, and the purpose and end of my invention is to overcome them.

My invention therefore consists of a furnace which clears or cleans itself of ashes as they are made and conducts them to a receptacle outside of the furnace, whence and in which they may be removed from the building, all as I will now proceed to particularly set forthand claim.

In the accompanyingdrawings, in the two figures of which like parts are similarly designated, Figure 1 is a perspective View of sufficient of a bricked furnacefor house-warming purposes to illustrate my invention, and Fig. 2 is a vertical section.

The furnace may be of any approved construction throughout; but beneath its grate a, I arrange a chute, b, highest at its inner end and the inner end of the grate, and incliningdownwardly and outwardly to the front door, c, of thefurnace, so that the ashes as they are made fall down this inclined chute and are carried away from beneath the grate, and consequently their accumulation under the grate is prevented. This chute has the closed rear wall, d, and the closed sides e, and its mouth f projects to a level with or slightly beyond the door to prevent the ashes from falling off the chute and direct them out of thefurnace. This construction, therefore, insures proper draft to the grate.

In front of and outside the furnace, and in line with the chute, is arranged an under ground pit7 g, to contain an ash-pan, h, which receives the ashes as they come from the chute.

This pit is covered by a door, il, hinged at j toward its rear end, so as to leave a projecting portion, 7c, extending into the chute. When v'the door z' is raised, as in full lines, Fig. 2, to

gain access to the ash-pan for its removal, then its projecting portion 7c extends across the mouth of the chute vertically, and closes it against the escape of ashes until the pan may be emptied and replaced and the door closed again. The door i may be pivoted in a inetallic frame, Z, surrounding the mouth of the pit g, as indicated in the drawings, and said door may also be provided with a ring, m, for operatingit. The chute is made of iron plate, and hence increases the heat-radiating surface ofthe furnace, its capability of4 self-cleaning always leaving it free of ashes. The incoming draft, however, keeps it at such a temperature as to preclude its being burned out by the-heat from the grate.

An additional very great advantage of this selfcleaning ash-pit is that it prevents the banking up of ashes beneath and in contact with the grate, and so prevents the burning out of the grate from beneath. By means of my self-cleaning ash-pit, also, the draft tothe fire is always free and unobstructed, and the fire may thus be kept bright and fresh. The ashes may be discharged directly into the pit and removed therefrom with a shovel as the pit is filled.

I do not claima stove or astove attahment or adjunct having the wall of the stove or a partition therein back of the grate inclined to discharge the ashes into the ash-pit. In my invention the chute is constructed as an article of manufacture that may be applied to the grateframe entirely independent of the walls IOO l of the heater, and to any kind of heater, and so, also, the ash-pit is independent of the furnace or heater itself. A

l. The combination,with a furnacevgrate, of a combined inclined air-induct and ash-discharge chute arranged directly beneath and con nected with such grate, and slanting from its rear toward its front, and having its discharge end at the front, and an ash-pit at such discharge end arranged outside of and away from the furnace, and a hinged cover for said ashpit, serving also as a cut-off for the chute, substantially as described.

2. The combination,with afurnace-grate, of an inclined chute arranged directly beneath CHARLES T. SCHOEN.
